Microsoft.Performance : The 'this' parameter (or 'Me' in Visual Basic) of 'ChangeDescriptor.ToString(object)' is never used. Mark the member as static (or Shared in Visual Basic) or use 'this'/'Me' in the method body or at least one property accessor, if appropriate.

Microsoft.Globalization : Because the behavior of 'DateTime.ToString(string)' could vary based on the current user's locale settings, replace this call in 'ChangeDescriptor.ToString(object)' with a call to 'DateTime.ToString(string, IFormatProvider)'. If the result of 'DateTime.ToString(string, IFormatProvider)' will be displayed to the user, specify 'CultureInfo.CurrentCulture' as the 'IFormatProvider' parameter. Otherwise, if the result will be stored and accessed by software, such as when it is persisted to disk or to a database, specify 'CultureInfo.InvariantCulture'.

Microsoft.Usage : Change 'Disposer.Dispose()' to call 'GC.SuppressFinalize(object)'. This will prevent derived types that introduce a finalizer from needing to re-implement 'IDisposable' to call it.

Microsoft.Design : Replace method 'Disposer.Timed(Action, Action<long>)' with an overload that supplies all default arguments.

Microsoft.Design : In externally visible method 'Disposer.Using<T>(Func<T>, Action<T>, Action<T>, Action<T>)', validate parameter 'factory' before using it.

Microsoft.Design : In externally visible method 'Disposer.Using<T>(Func<T>, Action<T>, Action<T>, Action<T>)', validate parameter 'before' before using it.

Microsoft.Design : In externally visible method 'Disposer.Using<T>(Func<T>, Action<T>, Action<T>, Action<T>)', validate parameter 'after' before using it.

Microsoft.Design : In externally visible method 'Disposer.Using<T>(Func<T>, Action<T>, Action<T>, Action<T>)', validate parameter 'meat' before using it.

Microsoft.Design : Consider a design where 'Guard.Is<T>(object, Func<Exception>)' doesn't require explicit type parameter 'T' in any call to it.

Microsoft.Naming : In method 'Guard.Is<T>(object, Func<Exception>)', correct the spelling of 'fnc' in parameter name 'fnc' or remove it entirely if it represents any sort of Hungarian notation.
